Yes, for all practical purposes they are considered "native" for public
adminstrative purposes.  There is, of course, no reliable records of those
introductions, but there is 1.  knowledge that certain plants were
cultivated by native Americans
2.  genetic comparison with populations from other geographic regions
(Mexico, Central America and other regions of North America)
where human transport seems to be the most reasonable explaination for the
distribution patterns.
3.  The greatest impacts to the natural ecosystems (that concern us most)
have occured within the recent 500 years.

Keep in mind that public policy and good science don't always agree.  But
that seems to be the most pragmatic way to handle it.
